Resolution to Comment to #15 March, 2008 Resolution to Comment to #15 Comment #15 How to deal with line spectra in the center frequency in case of SC-OOK mode? . Waiting on a number for the carrier leakage. Resolution Maximum line spectra in the carrier frequency is limited to less than 35 dB in case of 1 MHz RBW. Add text “SC-OOK shall meet the same PSD mask as SC, except the single line spectra at the carrier frequency.”

Carrier leakage in OOK 25dB 35dB Approximate value of line spectra 40 20 25dB 35dB -20 -40 PSD (dB) -60 Approximate value of line spectra Line spectra (dB) = 10log(OBW/RBW) OBW: Occupied Bandwidth RBW: Resolution Band Width -80 -100 RRC PA OBO=3dB, RBW=1MHz -120 PSD mask for SC -140 -5 -4 -3 -2 -1 1 2 3 4 5 Frequency (Hz) 9 x 10

Resolution to Comment to #113 March, 2008 Resolution to Comment to #113 Comment #113 OOK provides no befit when mask compliances is required at the transmit and operation with devices at neighboring channels is needed Resolution OOK has benefits for low power consumption, low complexity, lowest cost portable applications even when mask compliances is required. Add text “SC-OOK shall meet the same PSD mask as SC, except the single line spectra at the carrier frequency" Slide 4
